Fail building the project: Cannot find multiple modules

[EvsChen]

I'm new to webpack-cli and clone this project to build locally.

Describe the bug

I follow the instruction in CONTIBUTING.md and run the following.

yarn install 
yarn link 
yarn link webpack-cli

Everything works well and no errors.

Then I run yarn test to make sure everything is installed well. Then the TS2307 error: Cannot find module comes out.

What is the current behavior?

I just paste some of the first missing modules here, but the list is a lot longer.

> webpack-cli@3.1.0 build /Users/chenshenyue/webpack-cli
> tsc

packages/add/index.ts:1:30 - error TS2307: Cannot find module '@webpack-cli/generators/add-generator'.

1 import defaultGenerator from "@webpack-cli/generators/add-generator";
                               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


packages/add/index.ts:2:32 - error TS2307: Cannot find module '@webpack-cli/utils/modify-config-helper'.

packages/generate-loader/index.ts:2:25 - error TS2307: Cannot find module 'yeoman-environment'.

2 import * as yeoman from "yeoman-environment";

To Reproduce
Just follow the CONTIBUTING guide to setup the project using yarn as I listed before.

Additional context
node version: 8.12.0
yarn version: 1.7.0
npm version: 6.4.1

Hi!

In order to build the project you have to run the bootstrap command as well. We use lerna to orchestrate the packages

[EvsChen]

Thanks a lot @ematipico ! That's the missing piece I'm looking for. Would it be better to mention it in the CONTRIBUTING.md? Otherwise it seems misleading for newcomers.

[ematipico]

Totally legit! Feel free to send a PR if you want :)

Sure. I'll send a PR for this.

I used the wrong email to commit so I reopen another one. The cla bot informs me that I have to sign the CLA first. But the link it gives doesn't work.

[ematipico]

It does work for me

[EvsChen]

Don't know why it fails. I use some proxy and it finally works. Could you please help to review my PR? @ematipico
